' IMPROVEMENT IN SEAMlNG-MACHINES.

Specification forming part of Letters Patent N 0. 188,633, dated March20, 1877; application filed January 24, 1877.

To all whom it may concern Be it known that I, WILLIAM HIPPERLING, ofNew York, in the county of New York and State of New York, have inventeda new and useful Improvement in Machines for Crimping Sheet Metal, ofwhich the following is a specification, reference being had to theaccompanying drawings.

The invention relates to machines for crimping the edges of sheet-metalcans or recep tacles.

Great difficulty and inconvenience have heretofore been experienced inattaching the bottoms to cans or other sheet-metal vessels of an angularor relatively angular configuration. To obviate this difficulty andinconve'nieuce is the object of theinvention, which is effected byconstructing the crimping-head of a peculiar and novel shape, so thatits periphery adapts itself to crimp the metal upon an angularformer-head without jar or irregular action, and in providing a clutchof any construction, whereby a ready meansof removing the can or vesselafter the bottom has been attached is secured. The exact nature of theinvention is hereinafter fully set forth, from which and the drawingsits object will more fully appear.

In the drawings, Figure l is a side elevation, partly in section. Fig. 2is an end eleva- -tion, showing, particularly, the construction of theheads L and M.

In the accompanying drawings, A denotes the frame of the machine, whichis of usual construction. B is the axle or shaft of the former-head, and0 the axle or shaft of the crimping-head. The shaft B is provided withthe belt-wheel b and the cog-wheel c, which meshes with the cog-wheel 11upon the shaft 0. D is an interior frame adapted to support the shaft 0and other parts. The frame D is provided with bearings e, that aresecured in boxes 0 upon the main frame A, and is sustained so as to holdthe crimping-head free of the former-head by means of the spring h, theupper end of which is attached to the vertical support 1', that issecured to the frame A. The frame D, with the crimping-head, is

depressed at will by means of the treadle E, which is connected with theframe D by the rod k, and adapted to conveniently effect its offices inany appropriate manner. These elements and parts are not new, and theirconstruction and operation are so well understood that a more exactdescription of them need not be presented. The invention is embodied inthe features hereinafter specified.

To the upper section of the frame D are secured the brackets or supportsm, and in line therewith the supports it, the latter being attached tothe frame A. These brackets or supports serve to sustain the bent leverH, to effect Whichobject the pins 010 are provided, a horizontal slotbeing cut in the end of the lever to accommodate the former, and

an aperture to receive the latter. The depending end of the lever H isin the form of a yoke, at the ends of which are studs or warts T, whichrest in the groove 8 in the dead-wheel I, which turns or may be movedlaterally upon the shaft B. To the Wheel I is rigidly secured the boltor bayonet t, which is carried through a hole in the belt-Wheel b, andis of such length that when the lever H is actuated its free extremitywill obstruct the revolution of the projection u upon the wheel K, whichis rigidly attached to the shaft or axle B, whereby the shaft or axle Band all its adjuncts are caused to revolve simultaneously. By thisconstruction I provide a convenient form of clutch, whereby it ispracticable to check the rotation of the former-head at will-acircumstance of very great consequence, by reason of the fact that ifthe former-head is angular it is scarcely possible to remove the objectupon it while it is in motion, as may be done without difficulty if theformer is round.

To the outer end of the shaft or axle B is secured, in the customarymanner, the formerhead L, which, in the present instance, issubstantially in the shape of a parallelogram, but which may be of anyangular configuration in which sheet-metal vessels are fabricated.Gontiguous to it is the shield o, and it is constructed with thecustomary lip or raised rim,

so as to efl'ect the crimping of the edge of the sides of the can uponthe bottom, or the edge of the bottom upon the sides, at will, as may bepreferred but the head L difl'ers from other heads only in that it isangular in shape.

To the outer end of the shaft or axle O is secured, ll] the customarymanner, the crimping-head M, its axial center being in the samelongitudinal vertical plane as the axial center of the head L, the partshereinbefore mentioned being arranged and disposed accordingly. 1n thepresent instance the head M is constructed with relation to the shape ofthe particular former-head shown and described, being intended for usein the fabrication of cans or vessels of the shape of a parallelogrambut it may be adapted to cans or vessels of other angular shapes, as maybe desired.

The distinctive novelty of the crimpinghead M consists in the fact thatits periphery is provided with concavities or gradual depressions, whichtravel around the angles of the former-head, the concavities coinciding,to all intents and purposes, in length of outline with the length ofoutline of the angle to be crimped -less the space occupied by themetal. It is not essential that the proportions be exact, it being onlynecessary that allowance be made for the metal, the periphery of thecrimping-head being nearly or about equal to the periphery of theformer-head, and the concavities made to move upon the angles, so as topreserve an evenness of pressure as near as may be practicable. Thenearer the approximation to the exact relations stated the better willbe the resu t; but a satisfactory result will be attained even if theembodiment of the invention is somewhat removed from that particularlyrecommended. The elfect of this construction is, that the crimping ofangular cans or vessels is done with great ease and without jar assatisfactorily as in the case of those that are round.

It is apparent that the shape of the crimping-head M may be adapted touse, as hereinbefore stated, in the fabrication of cans or vessels ofany angular shape in which sheet-metal receptacles are constructed.

The operation of the machine will be readily understood from theforegoing description of its parts. Power having been applied, thebelt-wheel b moves free. upon the former-head L, and the treadle carrieddown. Thus the heads L and M are held together by means of the clutch,and these devices being rotated the process of crimping is speedilyefi'ected. The treadle is then allowed to rise, being elevated by theupward motion of the frame D, caused by the spring h, thus permittingthe belt-wheel b to move free. The can is then taken from theformer-head, and. the operation aforesaid repeated.

-What I claim as new and useful, and desire to secure by Letters Patent,is-

1. The crimping-head M, having four concavities or depressions in itsperiphery, substantially as shown and described, and for the purposespecified. I

2. The combination of the head M, having four concavities in itsperiphery, with the head L, having four angles upon its periphery,substantially as and for the purpose set forth.

3. A crimping-head the periphery of which is elongated by concavities ordepressions, for

the purpose set forth.

4. The combination of an angular formerhead with a crimping-head havingconcavities or depressions, substantially as set forth.

In testimony that I claim the foregoing improvement in machines forcrimping sheet metal, as above described, I have hereunto set my handthis 19th day of January, 1877.
